Application September 19,1938. Serial No. 230,713 3 Claims. 01. 103234)My invention appertain's to oil and water well constructions in general,and the principal object is to provide an improved structure remarkablysimple and economical in character and susceptibis "of adequatelyflowing the fluid under hand, and pressure regulated conditions atpredetermined intervals depending on the natural supply of fluid in thehole.

In keeping with underlying principles of reliable fluid control, thepreferred embodiment is characterized by a valved reservoir functioningas a trap, a conduit being connected thereto to feed air, underpressure, whereby to lift the fluid column, at desired intervals,through a pipeline leading to the receiving and storage tanks.

A further advantage'is derived from the adoption and use ofinterconnected piping having a valved by-pass incorporated therein,whereby to utilize the hand regulated air pressure to blow 2o clean theball check valve and its encompassing cage.

Other features and advantages may perhaps become equally well apparentfrom the succeeding description and accompanying terminal 5 Claims- I Inthe illustrative drawing, wherein like reference numerals designatecorresponding parts throughout the single view:

The figure structurally represents the preferred embodiment of theinvention as organized and particularly perfected under the principlesof this invention. I

Merely as a matter of convenience of description, it is to be assumedthat we are concerned with an oil well. Therefore, the excavation orhole I has leading thereinto to the desired depth an appropriate wellcasing 2. Above the surface and attached to the upper portion of thewell casing is a suitable casing head 3 having a pressure gage line 4 onone side and a gas vent pipe 5 on the opposite side.

The flow device is characterized essentially by an appropriatelyproportioned enclosure 6 forming the reservoir. This is of cylindricalcross 45 sectional form, in the main, and functions as a trap for theoil 1 to be lifted and withdrawn. The reduced lower end 8 is providedwith a packed fitting or collar 9, this being properly ported to allowthe incoming oil ill to enter the 50 trap. The upper reduced neckportion ll is joined by an appropriate coupling l2 to the barrel l3leading up through and beyond the casing head and terminating in asuitable stuffing box It.

The standing valve comprises an appropriate 55 cage IS on the lower endof the oil flow lifting exhausted from the trapping chamber.

pipe I. As is customary the cage houses a ball check valve II. The flowpipe I 6 leads up through andbeyond the stuiflng box where it isincommunicatlon with the discharge pipe l8, this leading. to the receivingand storage tanks (not I shown).

Parallel to the pipe II is the air pressure supply line or pipe I9, thisbeing connected to,the upper end portion of the barrel I3 to feed theair, under pressure, into the reservoir or trap 6. Ad- 10 jacent to thebarrel and in the line I9 is a suitable pressuredetector gage 20.Annexed in .the line is is a bleed pipe 2| having a relief cock'22. Nearthis is a cutoff-valve or cock 23. The crosspipe 24 is a by-pass andalso provided with a hand regulated cock 2!. This valved by-pass joinsthe lines I8 and I. The remaining cutoff cock 2B is in the line ll.

The ball valve at the bottom of the trap will admit fluid from the holewhenever air pressure 2 in the trap or reservoir is normal. Closing theair pressure valve 23 and opening the bleeder valve 22 insures this.When the trap chamber or reservoir has thus filled to the level .of thefluid Ill outside, this condition is indicated by the 5 cessation of airflow through the bleeder valve. Then the system is ready to initiate theexit flow.

The flow is accomplished by closing the bleeder valve 22 and opening thepressure regulating or cutofl' valve 23 to the proper pressure asindicated 30 by the height to which the fluid is to be lifted. Airpressure entering the tubing exerts pressure on the top of the column offluid I trapped in the chamber and in so doing closes the ball checkvalve. Hence the fluid 1 enters through the aper- 5 tured cage i5 and isforced up through the flow pipe I 6 and on out through the line iii tothe tank. It continues until all of the fluid has been Then the closingof the pressure valve and the reopening of the bleeder valve permitsmore fluid to flow into the trapping chamber, whenit is again set forthe next operation.

By closing the valve 22, the valve 26 and opening the valve 25, the aircan be shot down through the pipe-end II and through the pipeline l6 toclear the ball check valve of obstruction and to wash away the sand andsmall accumulation, etc.

It is thought that persons skilled in. the art to which the inventionrelates will be able to obtain a clear understanding of the inventionafter considering the description in connection with the drawing.Therefore, a more lengthy description is regarded as unnecessary.
